摘要:

为探讨甘草、高良姜、黄柏、北豆根、艾叶、连翘等6种中草药提取液对桃果实采后致腐真菌毛霉和青霉的抑制效果,采用生长速率法与活体果实接种孢子悬液法,对不同中草药提取液的抑菌效果进行对比,筛选出抑菌效果良好的中草药种类,并进一步通过体积浓度梯度稀释法,对其最小抑菌浓度(MIC)和最小杀菌浓度(MBC)进行了探讨。结果表明:不同中草药提取液对桃果实采后致腐真菌毛霉和青霉均有不同程度的抑制作用,其中甘草和连翘提取液的抑菌效果较强,黄柏和高良姜提取液的抑菌效果一般,艾叶和北豆根提取液的抑菌效果较弱。甘草和连翘提取液对毛霉的MIC均为培养液体积分数的25%、MBC均为培养液体积分数的50%;甘草和连翘提取液对青霉的MIC均为培养液体积分数的12.5%、MBC均为占培养液体积分数的25%。

Abstract:

The inhibition effects of 6 kinds of chinese herbal extracts against fungi(Mucor and Penicillium) causing decay on postharvest peach were studied in this paper.The 6 kinds of chinese herbal were glycyrrhiza,alpinia officinarum,phellodendron,asiatic moonseed,leaf of moxa and forsythia.The antibacterial effects of different chinese herbal extracts were comparatived by growth rate method and inoculation of spore suspension on peaches.The species of chinese herbal which had good inhibitory effects were selected.And the minimal inhibition concentration(MIC) and minimal bactericidal concentration(MBC) of chinese herbal which had good inhibitory effects were investigated by dilute with grads.The results showed that:different chinese herbal extracts had different inhibitory effects against fungi causing decay on postharvest peach.Glycyrrhiza and forsythia were the better kinds which against the Mucor and Penicillium in these 6 kinds of chinese herbal.Alpinia officinarum and phellodendron were the kinds with general inhibition.Leaf of moxa and asiatic moonseed were the weak inhibition kinds.The MIC of glycyrrhiza and forsythia extracts on Mucor all were that amounts of extracts in medium(v/v) were 25%,the MBC of glycyrrhiza and forsythia extracts on Mucor were 50%.And on Penicillium,the MIC of glycyrrhiza and forsythia extracts all were that amounts of extracts in medium(v/v) were 12.5%,the MBC of lycyrrhiza and forsythia extracts on Penicillium were 25%.
